In the article titled “Joint delay Doppler probability density functions for air-to-air channels,” International Journal of Antennas and Propagation, Volume 2014, Article ID 814218, 11 pages,, errors occurred in , , and .

(I) Equation . The semimajor axis and the semiminor axis in have to be calculated as The offset from the origin is correct.

(II) Equation . It should read as follows:

(III) Equation . It should read as follows: with being the concentration parameter of the distribution and being the centrality parameter of the distribution, that is, the place on the ellipse, where the dominant scatterers come from. The centrality parameter is given by and is the modified zeroth order Bessel function of the first kind.
